MACHINE FOR INSERTING SCREW-THREADED WIRE lN BOOT AND SHOE SOLES.

SPECIFICATION forming part of Letters Patent No. 244,046, dated July 12, 1881.

Application filed April 30, 1881. (No model.)

I To all whom it may concern Be it known that I, LOUIS GODDU, of Winchester, county of- Middlesex, State of Massachusetts, have invented a new and useful Improvement in Machines for Inserting Screw- Threaded Wire in Boot and Shoe Soles, of which the following description, in connection with the accompanying drawings, is a specification.

This invention in machines for inserting screw-threaded wire into boots and shoes is an improvement on United States Patent No. 171,610, dated December 28, 1875, to which reference may be had, and has for its object improvements in the mechanism or devices for cutting off the wire after it has been inserted into the sole or work, and either flush with the outer sole or into the channel in the outer sole, as may be desired. In the patent referred to the arms carrying the cutters were made to slide longitudinally, one with relation to the other, in opposite directions and transversely to the edge of the sole and the direction of the length of the channeL' Such construction required the expenditure of considerable power to operate the cutters, and the mechanism was not so simple as I desired, so I devised two levers, such as herein shown, to carry the cutters. I have so arranged and constructed these levers, mounted on a vertical pivot, that they open and close horizontally above the sole, the cutters carried by them moving in the direction of the length of the usual channel, or parallel with the edge of the sole. The cutters carried at the forward ends of these levers are so shaped that they may either cut olf a wire in the bottom of the channel, or by employing a guard, such as herein described, interposed between the levers and cutters and the sole, the wire may be cut off flush with the face of the outer sole. The under side of the front ends of the cutter-carryin g levers are provided with lips b to enter the channel in the sole when the fastenings are to be cut off in the channel.

Figurel represents, in vertical section, a sufficient portion of ascrew-insertin g machine, such as represented in my said patent, to illustrate my present invention. Fig. 2 is apartial view of Fig. 1, looking at it from the right, the

frame-work being broken away to show the cutting mechanism and its operative parts interposed between the levers, and to rest on the sole when the wire is to be cut off even with the face of the sole. Fig. 3 is a top view of a cutting mechanism, with the rocking shaft which imparts motion to the cutter-carrying levers in section. Fig. 4 is a side elevation of the levers and cutters with the guard turned back or away from under the lips of the lovers and the cutters, the lips and cutters being placed in and so as to cut off the wire in the channel of the outer sole, to be thereafter concealed by the channel-flap. Figs. 5 and 6 are details to be referred to; and Fig. 7 represents, in top view, front view, and longitudinal section, a modified guard.

This my present invention being an improvement on my patent referred to, I have deemed it unnecessary to show the devices for holding the wire a, or screwing it into the stock or sole, as such devices will be the same as are fully shown and described in the said patent.

The head E, lever M, and cam L to move it, and nose D are all substantially as in the said patent, where they are marked by the same letters. The cam L is carried by the rotating shaft B. (Shown in Fig. 1.)

The shoe or boot, into the sole of which the screw-threaded Wire a or the sole-fastening is to be inserted, will be held upon a horn, substantially as in the said patent.

The cam L, acting on the adjustable toe-piece l, vibrates the leverM about its fulcrum l causing the toothed sector at at the lower end of the said lever, by its engagement with thebevelpinion n, to oscillate the short shaft a and the hub-pinion n thereon, so that its teeth, in engagement with the teeth 8 t of the cutter-carrying levers c d, vibrate the said levers about their pivot e, the adjustable cutters g, fitted into diagonal grooves at the front ends of the said levers, (see Fig. 6,) and kept therein by caps f and screws 2, being moved toward and from each other in a line corresponding with the length of the channel and the edge of the sole, the cutters cutting offthe wire with great ease after it has been inserted into the sole.

The under side of the cutter-carrying levers 0 cl, at their front ends, will preferably be provided with downwardly-extended lips I), of such length as to enter the usual channel of the sole h when the guard is is removed or turned aside from below the cutters and nose D, as in Figs. 4 and 5, about the screw 3 as a center. When the wire is to be cut off flush with the bottom of the sole the guard will remain attached by the screws 3 and 4, as in Figs. 1 and 2, and

full lines, Fig. 5, and, resting directly on the sole, will keep the cutters at the level of the outer surface of the sole.

Pivoting the levers 0 d, as described, and operatin g their long arms by the hub-gear n affords a very powerful and certain means for actuating the cutters to cut off the wire-means much more durable and simple than that shown in my patent referred to-and also enables the cutters to open and close in the channel.

The guard 70 may be made from one or two pieces of metal, and may have made in its forward end either an oblong opening, 8, as at Figs. 1 and 5, countersunk at top for the reception of the cutters and lips, or may be left open at one end, as at Fig. 7.

In Fig. 7 the guard is composed of a thin piece, 10, of steel struck or bent into proper form, and having connected with it by pins 13 the thicker portion 12 of steel. This gage or removable guard, located below the ends of the levers and their cutters, to be readily and quickly interposed between the arms and their cutters and the sole to change from cutting oif the wire in the channel to cutting it off flush with the sole, and vice versa, is a matter of very great convenience in the manufacture of boots and shoes.

I do not broadly claim a guard or shield interposed between the cutters and sole, as such a device was contrived by Wm. H. Cuff. The Gulf plan of shield could not cut off a fastening in the channel.

I claim- 1. In a machine for inserting screw-threaded wire into boot and shoe soles, the horizontal levers c d, and cutters connected therewith, combined with the guard 70, provided with the opening for the passage of the wire being inserted in the sole, the said guard being located between the said levers and horn and with relation to the cutters, as described, to thereby maintain the said cutters sufficiently above and so as to cut ofi the wire level with the sole, substantially as set forth.

2. In a machine to insert screw -threaded wire into boot and shoe soles, the pivoted horizontal levers c d, provided at their outer ends with the downwardly-extended lips I), combined with the cutters 9, held in the'said levers and extended down below the said lips, the latter entering the channel in the sole, while the cutters cut off the wire within the said channel, substantially as described.

3. The cutter-carrying levers c d, provided with teeth, as described, combined with the oscillating shaft at, having the hub-gear and bevel-gear, and with the vibrating lever M, having the toothed sector m, to oscillate the said shaft, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

LOUIS GODDU.
